Safety protection system for high and low voltage electrified body

Abstract

The invention discloses a safety protection system for high and low voltage electrified bodies. The system includes a high voltage electrified body, a low voltage electrified body, a high voltage switch trip circuit, an approach monitoring subsystem, a voltage detection subsystem and an electrified warning subsystem; the approach monitoring subsystem Monitor the approaching target through the microwave probe and transmit the monitoring signal to the AND gate logic module, which is connected to the high voltage switch trip circuit; the voltage detection subsystem detects the voltage of the high / low voltage electrified body through the measurement unit and transmits it to the high / low voltage signal acquisition and processing module, the high-voltage signal is transmitted to the AND gate logic module and works together with the monitoring signal to control the tripping of the high-voltage switch; the live warning subsystem includes a high / low voltage warning light and a power display, and is connected to a high / low voltage signal acquisition and processing module for live warning and display. This system enables operators who mistakenly approach electrified bodies or mistakenly remove electrified wires to be warned in time, thereby avoiding electric shock accidents and ensuring personal safety.

Description

technical field [0001] The invention relates to a safety protection system for a high and low voltage electrified body. Background technique [0002] Electric shock accidents account for a large proportion of all kinds of accidents in related industrial and mining enterprises. The main factors of electric shock accidents are the wrong switch position, approaching or contacting live high-voltage bodies, misidentifying equipment or mistakenly dismantling low-voltage live terminals. [0003] The protection of electrical equipment has developed from electromagnetic type and integrated circuit type to microcomputer type protection and photoelectric type protection that has not yet become the mainstream. The development of various forms of protection technology is changing with each passing day. The more convenient, the more powerful the functions, but it has been stagnant in terms of the safety protection of the users of electrical equipment. For electric shock accidents, the hig...

Problems solved by technology

[0004] The reason for this situation is that the protection of high and low voltage charged bodies is still at the level of passive protection, which depends on the completeness of the safety system and the subjective initiative of employees.
